A carbon resistor
Photographers Direct were requesting image of different types of resisters. I contacted a local teacher and borrowed a whole set from physics lab rehostats to small carbon resistors (as shown here).
None of the images sold via photographers direct, however several of them DID sell some time later via Alamy. Resistance is NOT useless!
